You do not export your bookmarks, contacts, passwords,
etc from the iPad into Mail. But there several other options
- Backup your data to iCloud
- backup your data to iTunes on your Mac
- Set your iPad to use contacts, passwords, mail settings, Safari, etc. from iCloud
In any case rather than doing a full erase and reset simultaneously press and hold the Home button (round button at the bottom of the screen) and the quit button (rectangular button near the top of the screen) and hold until the screen goes blank and the white Apple logo appears then wait patiently for the reboot to complete. This does not erase any apps or data and if that does not work the next step is to go to the Genius Desk.
